All I can say about login issues are that we are at the mercy of your e-mail provider.We have no ability to force mail to go to you, we just send it, like we send every other e-mail.If your provider blacklisted WZ for whatever reason, we can't do anything about it!

It is best to use a gmail account, since those haven't failed for anyone that I know of.

Also, lots of times, people mistype their e-mail address, and if you do that, sorry, we can't fix that either, you need to make another account.
